Say the words "sports car made in Germany" and many people will think of Porsche. Its cars have always been the ones to beat on the race track but now there's a challenger vying for Porsche's crown. The BMW Series 1 M Coupe is set to take on Porsche's lightweight track missile, the Cayman R. Both cars have six-cylinder engines and nearly identical performance. The BMW has the engine in the front, the Porsche has it in the back, but both are rear-wheel drive. Can the BMW pull ahead of the Porsche?
